ADJUSTMENT

1. PRECAUTION (w/ Air Suspension) NOTE: Be sure to read Precaution thoroughly before servicing. Refer to «PRECAUTION»(ref-400816-S40570634362011051800000) .
2. PRECAUTIONS AND WORK DESCRIPTION The U660E automatic transaxle does not have an oil filler tube and oil level gauge. When adding fluid, add fluid through the refill hole on the transaxle case. The fluid level can be adjusted by draining excess fluid (allowing excess fluid to overflow) through the No. 1 transmission oil filler tube of the oil pan. HINT: "Overflow" indicates the condition under which fluid comes out of the overflow plug hole. Before adjusting the fluid level, add the specified amount of fluid when the engine is cold and warm up the engine to circulate the fluid in the transaxle. Ensure that the fluid temperature is as specified and the engine is idling. The U660E automatic transaxle requires Toyota Genuine ATF WS. The adjustment should be performed according to the procedures and notes.
3. WORK FLOW The adjustment should be performed according to the procedures referenced in the work flow below.
4. BEFORE FILLING TRANSAXLE WITH FLUID Lift the vehicle. NOTE: Set the vehicle on a lift so that the vehicle is kept level when it is lifted up. Remove the 2 bolts, clip and front fender apron seal LH.
5. PERFORM INITIAL FILLING NOTE: If the transaxle is hot (ATF temperature is high), wait until the fluid temperature becomes the same as the ambient temperature before starting the following procedure. (Recommended ATF temperature: around 20°C [68°F]) Remove the refill plug and gasket from the automatic transaxle. NOTE: After performing any of the following operations, it is not necessary to perform the initial filling procedure. Proceed to 6 the Add Specified Amount of Fluid procedure. Operations that do not require initial filling Disconnection of the oil cooler tube or oil cooler hose Repair of fluid leak due to a loose case plug, or a faulty plug gasket or O-ring Installation of a new transaxle with torque converter (filled fluid parts) Using a 6 mm hexagon socket wrench, remove the overflow plug and gasket from the automatic transaxle. NOTE: If ATF comes out after removing the overflow plug, wait until the fluid flow slows and only drips come out. If ATF comes out, it is not necessary to perform the initial filling procedure. After checking the tightening torque of the No. 1 transmission oil filler tube, temporarily tighten the overflow plug. Using a 6 mm hexagon socket wrench, check that the No. 1 transmission oil filler tube is tightened to the specified torque. TEXT IN ILLUSTRATION *1 No. 1 Transmission Oil Filler Tube *2 Hexagon Socket Wrench *3 Overflow Plug Hole Torque: 1.7 N*m (17 kgf*cm, 15 in.*lbf) NOTE: If the No. 1 transmission oil filler tube is not tightened to the specified torque, the amount of fluid cannot be precisely adjusted. HINT: To check the torque of the No. 1 transmission oil filler tube, insert the socket hexagon wrench into the overflow plug hole. Perform initial filling. Fill the transaxle through the refill hole until fluid begins to trickle out of the overflow plug hole. NOTE: Use Toyota Genuine ATF WS. Wait until the fluid flow slows and only drips come out. Temporarily install the overflow plug. HINT: Reuse the old gasket. The plug will be removed again to adjust the fluid level.
6. ADD SPECIFIED AMOUNT OF FLUID Fill the transaxle with the correct amount of fluid as listed in the table below. NOTE: Refill amount differs depending on the operation that was performed. Standard Capacity Performed Repair Fill Amount Disconnection of the oil cooler tube or oil cooler hose Repair of fluid leak due to a loose case plug, or a faulty plug gasket or O-ring Installation of a new transaxle with torque converter (filled fluid parts) 0.5 liters (0.5 US qts, 0.4 lmp. qts) Removal and installation of the drive shaft Removal and installation of the transaxle case oil seal Removal and installation of the oil pan 2.8 liters (3.0 US qts, 2.5 lmp. qts) Removal and installation of the valve body 3.2 liters (3.4 US qts, 2.8 lmp. qts) Removal and installation of the transaxle (not including removal of the torque converter) 3.4 liters (3.6 US qts, 3.0 lmp. qts) Removal and installation of the torque converter (torque converter reused) 4.8 liters (5.1 US qts, 4.2 lmp. qts) Installation of a new torque converter 5.3 liters (5.6 US qts, 4.7 lmp. qts) Temporarily install the refill plug to avoid fluid spillage. HINT: Reuse the old gasket. The plug will be removed again to adjust the fluid level. Lower the vehicle.
7. ADJUST FLUID TEMPERATURE When using the Techstream: HINT: The actual ATF temperature can be checked on the Data List using the Techstream. Connect the Techstream to the DLC3 with the engine switch off. Turn the engine switch on (IG) and turn the Techstream on.

Depress and hold the brake pedal. Start the engine. Slowly move the shift lever from P to D, then back to P. HINT: Slowly move the shift lever to circulate the fluid through each part of the transaxle. While observing the D shift indicator on the combination meter, move the shift lever back and forth between N and D at an interval of 1.5 seconds for 6 seconds or more. NOTE: Do not pause for more than 1.5 seconds. HINT: Performing this operation will cause the vehicle to enter the fluid temperature detection mode. Check that the D shift indicator comes on for 2 seconds. HINT: When the fluid temperature detection mode is activated, the D shift indicator on the combination meter comes on for 2 seconds. If the D shift indicator does not come on for 2 seconds, return to the step where terminal TC is first connected and perform the procedure again. Move the shift lever from N to P. Release the brake pedal. Select the Active Test menu: Connect the TC and TE1 / OFF. NOTE: Be sure that terminals TC and TE1 are not connected. If the terminals are connected, the fluid level cannot be precisely adjusted due to fluctuations in engine speed. HINT: Disconnecting terminals TC and TE1 activates the engine idle speed control mode. In the engine idle speed control mode, engine idle speed control starts when the fluid temperature becomes 35°C (95°F) or more and the engine speed is maintained at approximately 800 rpm. Even after terminals TC and TE1 are disconnected, the fluid temperature detection mode is active until the engine switch off. Warm up the engine with the engine idling until the fluid temperature reaches the normal operating temperature (40 to 45°C [104 to 113°F]). Below Normal Operating Temperature Normal Operating Temperature Above Normal Operating Temperature 40°C or less (104°F or less) 40 to 45°C (104 to 113°F) 45°C or more (113°F or more) NOTE: If the fluid temperature is within the normal operating temperature range, immediately proceed to 8 the Adjust Fluid Level procedure. If the fluid temperature is 45°C (113°F) or more, stop the engine and wait until the fluid temperature drops to 40°C (104°F) or less.

HINT: Slowly move the shift lever to circulate the fluid through each part of the transaxle. While observing the D shift indicator on the combination meter, move the shift lever back and forth between N and D at an interval of 1.5 seconds for 6 seconds or more. NOTE: Do not pause for more than 1.5 seconds. HINT: Performing this operation will cause the vehicle to enter the fluid temperature detection mode. Check that the D shift indicator comes on for 2 seconds. HINT: When the fluid temperature detection mode is activated, the D shift indicator on the combination meter comes on for 2 seconds. If the D shift indicator does not come on for 2 seconds, return to the step where terminal TC is first connected and perform the procedure again. Move the shift lever from N to P. Release the brake pedal. Remove SST from terminals 13 (TC) and 4 (CG). TEXT IN ILLUSTRATION *1 DLC3 SST: 09843-18040 NOTE: Be sure that terminals TC and CG are not connected. If the terminals are connected, the fluid level cannot be precisely adjusted due to fluctuations in engine speed. HINT: Disconnecting terminals TC and CG activates the engine idle control mode. In the engine idle speed control mode, engine idle speed control starts when the fluid temperature becomes 35°C (95°F) or more and the engine speed is maintained at approximately 800 rpm. Even after terminals TC and CG are disconnected, the fluid temperature detection mode is active until the engine switch is turned off. Allow the engine to idle until the D shift indicator comes on again. D SHIFT INDICATOR Below Normal Operating Temperature (40°C or less) (104°F or less) Normal Operating Temperature (40 to 45°C) (104 to 113°F) Above Normal Operating Temperature (45°C or more) (113°F or more) OFF ON Blinks NOTE: If the D shift indicator is on, immediately proceed to 8 the Adjust Fluid Level procedure. If the D shift indicator blinks, stop the engine and wait until the fluid temperature drops to 40°C (104°F) or less (the indicator goes off). Then perform the Adjust Fluid Temperature procedure again from the beginning. HINT: In the fluid temperature detection mode, the D shift indicator comes on, goes off, or blinks depending on the fluid temperature. Fluid filling procedure should be performed when the D shift indicator is on (the fluid temperature is within the normal operating temperature range).
8. ADJUST FLUID LEVEL WARNING: Use caution while the engine is idling and the radiator fan is operating. Lift the vehicle. NOTE: Set the vehicle on a lift so that the vehicle is kept level when it is lifted up. Adjust the fluid level. Using a 6 mm hexagon socket wrench, remove the overflow plug and gasket. WARNING: Be careful as the fluid coming out of the overflow plug hole is hot. Check the amount of fluid that comes out of the overflow plug hole. NOTE: If only a small amount of fluid (approximately 1 cc) comes out of the overflow plug hole, then only fluid remaining in the No. 1 transmission oil filler tube has come out. This condition is not considered as overflow, so it is necessary to add fluid. If the amount of fluid that comes out of the overflow plug hole is large, wait until the fluid flow slows and only drips come out. If no fluid comes out of the overflow plug hole, remove the refill plug and gasket. Then add transaxle fluid through the refill hole until fluid comes out of the overflow plug hole. Wait until the fluid flow slows and only drips come out. NOTE: Use Toyota Genuine ATF WS. Check that the fluid flow has slowed and only drips come out. HINT: The fluid flow will not completely stop because the fluid expands as its temperature increases. Install the overflow plug with a new gasket. Torque: 40 N*m (408 kgf*cm, 30 ft.*lbf) Install the refill plug with a new gasket. Torque: 49 N*m (500 kgf*cm, 36 ft.*lbf) Lower the vehicle. Turn the engine switch off. HINT: Turning the engine switch off exits the fluid temperature detection mode. Remove the Techstream from the DLC3 (when using the Techstream).
9. AFTER FILLING TRANSAXLE Lift the vehicle. Clean each part. Check for fluid leaks. Install the front fender apron seal LH with the 2 bolts and clip. Lower the vehicle.
